Need some help, suddenly, my winetricks wouldn't work properly. Its like forever loading.

I've been experiencing the same thing here using the latest wrapper. It takes several minutes to load up the dialog box where you select what to install. It also takes several minutes once it's finished installing.

This is the first release candidate for the upcoming Wine 1.6. It
marks the beginning of the code freeze period. Please give this
release a good testing to help us make 1.6 as good as possible.

What's new in this release (see below for details):
- New implementation of the typelib creation support.
- GLSL-based support for fixed function vertex shaders.
- Support for desktop launchers in virtual desktop mode.
- Fixes for Japanese vertical text.
- New Croatian translation.
- Various bug fixes.

both of those are new enough that they *should* work... except in your original post you said your using 10.7.5, and he maker said he created and tested in 10.8. Its possible there are some nvidia driver issues or 10.7 issues.

If you do a Test Run inside Wineskin.app -> Advanced and get logs it may help to show whats going on when it freezes...

For starters, there is a reason these wrappers have such small filesizes. They are not the full game.
When you download a wrapper, you also need to have the PC version of the game (in which you would install INTO the wrapper). When you select 'install software', you need to find the setup.exe file that is used by the windows game to install the game into the wrapper, just as it would be used to install the game onto a windows computer.
